API to get captions from images, using OFA captioning method

OFA Repo link https://github.com/OFA-Sys/OFA.git

To use this, download the captioning checkpoint from https://ofa-beijing.oss-cn-beijing.aliyuncs.com/checkpoints/caption_large_best_clean.pt Or refer the model card and download the required model https://github.com/OFA-Sys/OFA/blob/main/checkpoints.md

Rename that file to "checkpoints.pt" Move checkpoints.pt to a folder named checkpoints and the folder checkpoints should be in the main directory

The directory should look like this

The checkpoints folder should contain the captioning checkpoint/model file (checkpoint.pt) as shown

Overall directory structure should look like this

Now the docker image can be built using the Dockerfile
